    摘要: A MOSFET transistor structure is formed in a substrate of semiconductor material having a first conductivity type. The MOSFET transistor structure includes an active region that is surrounded by a perimeter isolation dielectric material formed in the substrate to define a continuous sidewall interface between the sidewall dielectric material and the active region. Spaced-apart source and drain regions are formed in the active region and are also spaced-apart from the sidewall interface. A conductive gate electrode that is separated from the substrate channel region by intervening gate dielectric material includes a first portion that extends over the substrate channel region and a second portion that extends continuously over the entire sidewall interface between the isolation dielectric material and the active region. Thus, an enclosed ring is maintained around the entire composite perimeter, thereby completely avoiding regions of high trap density and, thus, preventing any current path for gate induced drain leakage (GIDL) to occur.

    摘要: An integrated circuit trim structure includes a dopant source, a target trim element formed in proximity to the dopant source, and a conductive heating element. The heater element is formed in proximity to the dopant source and includes first and second terminals and a trapezoid shaped region formed between the first and second terminals. As predefined current pulse is applied to the first terminal to promote current flow between the first and second terminals, a local heat source is created at a predefined location within the trapezoid shaped region and in proximity to the dopant source such that dopant flows from the dopant source into the target trim element to change the conductive characteristics of the target trim element.

    摘要: The integration period of an imaging cell, or the time that an imaging cell is exposed to light energy, is substantially increased by utilizing a single-poly, electrically-programmable, read-only-memory (EPROM) structure to capture the light energy. Photogenerated electrons are formed in the channel region of the EPROM structure from the light energy. The photogenerated electrons are then accelerated into having ionizing collisions which, in turn, leads to electrons being injected onto the floating gate of the EPROM structure at a rate that is proportionate to the number of photons captured by the channel region.
